Google Bourbon Update (May 2005): What It Was and What It Means Today

The Google Bourbon update was a round of ranking changes that forum members named on 20 May 2005 and that ran until roughly 8 June 2005. It is reported to have changed how Google handled duplicate content and non-canonical URLs, and to have reduced the value of low-quality reciprocal and off-topic links. The short takeaway: give every page one clean URL, and only link to sites that make sense for your visitors.

This article is one entry in my full list of Google algorithm updates. Bourbon is a 2005 update, so nobody is losing traffic to it today, but the two problems it went after still turn up in almost every audit I run.

Detail	Information

Rollout finished	Around 8 June 2005 (approximate)
Rollout length	Roughly three weeks; both dates are approximate
Confirmed by Google	Partially: GoogleGuy (Matt Cutts) posted progress updates on WebmasterWorld, but the details of what changed came from SEO observers
Official source	No Google announcement page; earliest report: Search Engine Roundtable

What the Bourbon update changed

Google never published a description of Bourbon, so what we know comes from the people watching results at the time. Two themes appear consistently across the histories:

• Duplicate content and non-canonical URLs. Search Engine Land describes Bourbon as changing how Google treated duplicate content and non-canonical URLs. In 2005 this usually meant the same page being reachable at several addresses, such as with and without www, or with tracking parameters, and Google having to decide which one counted.
• Link quality. Bruce Clay’s update history lists the targets as duplicate content, non-thematic linking, low-quality reciprocal links and fraternal linking. Non-thematic linking means links between sites with nothing in common. Fraternal linking is usually understood as sites owned by the same people linking to each other to inflate their importance.

The update was named after Bourbon Street in New Orleans, the host city of an upcoming WebmasterWorld conference, following the forum habit of the time of naming updates in the style of hurricanes.

Timeline

• 17 May 2005: Search Engine Roundtable reported movement in Google’s results.
• 20 May 2005: WebmasterWorld members named the update “Bourbon”.
• Late May to early June 2005: GoogleGuy (Matt Cutts) posted updates on WebmasterWorld about how the rollout was progressing.
• Around 8 June 2005: the approximate end date given by Search Engine Land.

Who was affected

As reported at the time, the sites that moved were those with duplicate or non-canonical content and those that depended on reciprocal or off-topic links for their rankings. There were also reports that some sites which had been held back in what SEOs called the “sandbox” (the period in which new sites struggled to rank) moved during Bourbon. That is an observation from the forums, not something Google confirmed.

How to tell if the Bourbon update hit your site

You cannot check a 2005 drop with Search Console, because Search Console data does not go back that far. What is useful is knowing how the same pattern shows up now, because the underlying problems have not gone away.

Duplicate URL symptoms

• In Search Console, open the Page indexing report and look at “Duplicate without user-selected canonical” and “Duplicate, Google chose different canonical than user. A long list here means Google is making the choice for you.
• Use the URL Inspection tool on an important page and compare the “User-declared canonical” with the “Google-selected canonical”. If they differ, your signals are mixed.
• Type your domain with and without www, and with http and https. All four should end on one version through a single redirect.
• In the Performance report, filter by page. If impressions for one piece of content are split across two or three URLs, you have the Bourbon problem in modern form.

Link pattern symptoms

• A “links” or “partners” page full of unrelated sites that link back to you.
• A network of your own sites all linking to each other in the footer.
• Most of your referring domains having no topical connection to your business.

How to recover from the Bourbon update

The advice at the time, as recorded in the update histories, was to consolidate duplicates and step back from low-quality link exchanges. Sites that had dropped out of the index entirely could ask Google for reinclusion, which Matt Cutts mentioned in his comments. Here is how I would apply that today.

Problem	Fix
Site loads on www and non-www, or http and https	Pick one version and 301 redirect the others to it, site-wide
One product or article on several URLs (parameters, print versions, category paths)	Choose the main URL, add rel=canonical on the variants, and link internally only to the main URL
Near-identical pages targeting the same query	Merge them into one stronger page and redirect the rest
Reciprocal link pages and “partners” directories	Remove them or keep only links you would show a customer
Cross-linking between your own unrelated sites	Remove sitewide footer links; keep only links that genuinely help a visitor

One change since 2005 matters here. Google introduced rel=canonical in 2009, so you now have a direct way to tell Google which URL is the main one, rather than hoping it works it out. If you want a second pair of eyes on canonical and duplicate URL issues, that is a standard part of my technical SEO services. For the link side, I cover what kind of links are worth having in my off-page SEO services.

Is it still relevant today?

Bourbon itself is history. The ideas behind it are not. Canonicalisation and duplicate content handling are still core parts of how Google indexes the web, and Google’s guidelines still treat excessive link exchanges as a link scheme. If anything, the pattern is easier to spot now because the tools are better.

Frequently asked questions

When was the Google Bourbon update?

Movement was first reported on 17 May 2005, the update was named on 20 May 2005, and Search Engine Land puts the end at around 8 June 2005. All of these dates are approximate.

Did Google confirm the Bourbon update?

Partially. Matt Cutts, posting as GoogleGuy, gave progress updates on WebmasterWorld, but Google did not publish a description of what changed. The targets listed in update histories come from SEO observers.

Why was it called Bourbon?

It was named after Bourbon Street in New Orleans, where WebmasterWorld was about to hold a conference.

Is reciprocal linking still a problem?

Occasional links between related businesses are normal. Excessive link exchanges done to manipulate rankings are listed by Google as a link scheme, so a page of swapped links is still a liability.
